For solar panels to perform at their optimal efficiency they will require maintenance cleanings.
While dust and pollen are naturally removed by rain, bird droppings and algae are not. Once your panels start to appear dirty, it's a good idea to clean them.
How should you clean your panels?
If you plan on cleaning them yourself its best to use just water and a non-abrasive sponge to apply soapy water.
If you are thinking about using a pressure washer to clean them, it's advised to use only a normal garden hose as using anything with high pressure may cause damage.
For safety, its best to clean them from the ground with an extension pole. Remember... clean solar panels are not worth the risk of falling off your roof!
The best & safest way is to have your panels cleaned by an insured professional.
How we clean solar panels
We utilize the process of WFP cleaning(water-fed pole cleaning). This entails using reverse osmosis and de-ionization filters to purify your water. That purified water is then fed through an extension pole to a soft brush which is used to gently loosen all the dirt and debris. Finally we use the purified water to rinse away all the dirt(for an example watch the video).
Why use purified water and not soap? Soaps can leave a film or residue that not only shades panels like the dirt that was just washed off but can also encourage dirt to stick and build up faster.
Using the WFP process not only cleans the panels but also leaves them with a spot-free shine that's as beautiful as the first day they were installed.
If you have solar panels at your home or business we would love help you clean and maintain them!
